Self-consistent thermal-opto-electronic model for the dynamics in high-power semiconductor lasers

Published in:

Abstract:

High-power broad-area diode lasers (BALs) generate significant heat, impacting performance. A 2+1 dimensional traveling wave (TW) model incorporates heating effects through an iterative coupling of electro-optical (EO) and heat-transport (HT) solvers. This method analyzes heat sources, temperature profiles, and thermally induced refractive index changes.
